Boost the bass in a song

TutuAudio boosts bass with a low-shelf filter; you set the strength and built-in clipping protection keeps it from distorting. It runs in your browser with no upload; free, no sign-up. Phone speakers can’t reproduce very low frequencies, so listen on headphones to hear the effect.

Record

MP3, WAV, M4A, AAC, FLAC, OGG, WebM and the audio in MP4 videos

Everything runs in your browser — the file never leaves this device

Drop in a song, drag the strength slider, and the low end fills out — easiest to hear on headphones.

FAQ

Why can’t I hear a difference on my phone speaker?
Phone speakers physically can’t play very low frequencies, no matter how much you boost. Use headphones or a proper speaker.
Will too much bass distort?
Clipping protection keeps the peaks in check so it won’t crackle. At full strength the mix can sound boomy, so find the level that sounds right to you.
Is my song uploaded to your server?
No. The bass boost runs in your browser; the file never leaves your device.
Is it free? Do I need an account?
Free, no account, no usage limits, and no watermark on the export.
